Usage

Twitter Bootstrap FormBuilder is designed to output all the markup required to build horizontal forms,
with minimal typing.

After installing the Gem, you can use the special form_for helper by mixing TwitterBootstrapFormBuilder::Helper
into your Helper modules, which will automatically add the form-horizontal class to your <form> tag,
and set the :builder to TwitterBootstrapFormBuilder. That is, the following are roughly equivalent:

Note that both the label and input elements are still wrapped in <div class="field_with_errors"> by the base
FormBuilder. In addition, a <p class="help-block"> is output below the field containing the error message.
